About this service
Duct Replacement
Your air conditioner can only cool your home as well as your ductwork delivers the air. In South Florida, ducts live in some of the hottest attics in the country, and after years of summer heat, flex duct sags, inner liners tear, insulation flattens and connections pull loose. ENERGY STAR estimates that in a typical house, about 20 to 30 percent of the air moving through the duct system is lost to leaks, holes and poorly connected ducts. In a Florida attic, that cooled air is simply gone, and leaky return ducts pull hot, humid attic air back into your home.
Swift Air Conditioning specializes in whole-home duct replacement. We don't just swap old ducts for new ones in the same layout. Our team designs every system in-house, starting with a room-by-room Manual J load calculation to find out how much cooling each room actually needs, then a Manual D duct design that sizes every supply run, trunk line and return to deliver that airflow. Our goal on every job is every bedroom within 3°F of the thermostat, which matches the room-to-room comfort guideline in ACCA's Manual RS.
Installation is where good designs succeed or fail. Our crews seal every joint with mastic, insulate the new ducts for a Florida attic, support them so they can't sag, add return paths so closed bedrooms keep getting air and seal the connections at the air handler. We pull the permit, schedule the inspection and finish by measuring the airflow at every register and balancing the system.
Signs you may need new ductwork include rooms that never cool down, rising electric bills, dust that returns right after cleaning, a musty smell when the AC starts, sweating vents and ducts that are crushed, torn or disconnected in the attic. If your home still has its original ducts, or they've been patched through several AC replacements, a free in-home quote will show you what you have and what it would take to fix it. We serve homes from Vero Beach to Fort Lauderdale, and our team speaks Spanish. Call (561) 685-8408 to schedule your free quote.

Frequently asked questions
A room-by-room Manual J load calculation and a Manual D duct design done in-house, removal of the old ductwork, new ducts sealed with mastic, insulated and properly supported, return paths for bedrooms, sealed air handler connections, the permit and inspection, and a final airflow test and balance.

ACCA's Manual RS comfort guidelines call for each room served by a thermostat to stay within 3°F of the thermostat setting while cooling. That's the target we design and balance to. After installation, we measure airflow and room temperatures to confirm the new duct system delivers it.
Common signs are rooms that are always warmer than others, high electric bills, dust that keeps coming back, a musty smell when the AC starts, sweating vents and ducts in the attic that are crushed, torn or disconnected. Ducts that are original to an older home, or have been patched through several AC replacements, are also worth checking.
Yes. Replacing ductwork is permitted mechanical work. Swift pulls the permit with the building department that covers your address, whether that's a city, a village or the county, and schedules the inspection, so you don't have to handle any of the paperwork.
Often, yes. A new high-efficiency system connected to leaky, undersized ducts can't deliver its rated comfort or efficiency, and the duct design should match the new equipment. We inspect the ducts during the quote and tell you honestly whether they can be sealed and reused or should be replaced at the same time.
Most single-family homes take one to two days, depending on size, attic access and how many returns we add. Larger homes or homes with more than one system can take longer, and condos are often faster. We give you the schedule with your free quote.
